and form, on the base image, a patch corresponding to an image formed on a medium by the image former, the hardware processor causes the image former to form a patch corresponding to the medium based on a result of reading the medium by the reader; and add a white base to the patch corresponding to the medium based on determination that the reading result is not appropriate for analysis of the patch corresponding to the medium. ### Claim 2 (depends on 1) The image inspection system according to claim 1, wherein in a case where an image formed on a medium by the image former includes a covering image, the hardware processor causes the image former to form a patch corresponding to the covering image on the medium. ### Claim 3 (depends on 1) The image inspection system according to claim 1, further comprising: an identifier that acquires information about the medium based on the read image and identifies the medium. ### Claim 4 (depends on 3) The image inspection system according to claim 3, wherein the information about the medium includes at least one piece of information about a type of the medium and information about a characteristic of the medium. ### Claim 5 (depends on 1) The image inspection system according to claim 1, further comprising: an acquisitor that acquires information about a type of the medium, wherein the hardware processor identifies the medium based on a result acquired by the acquisitor. ### Claim 6 (depends on 1) The image inspection system according to claim 1, wherein the hardware processor causes the image former to add a white base to the patch in a case where the reading result includes a characteristic that a relationship between an increase/decrease in a developer and a reading gradation is partially inverted. ### Claim 7 (depends on 1) The image inspection system according to claim 1, wherein in a case of forming, on the medium, the patch to which a white base is added, the hardware processor performs control different from control when the white base is added to user content with respect to addition of the white base. ### Claim 8 (depends on 1) The image inspection system according to claim 1, wherein in a case where a specific image is repeatedly included in a background including the medium based on the reading result, the hardware processor causes the image former to form a patch corresponding to repetition of the specific image on the medium. ### Claim 9 (depends on 1) The image inspection system according to claim 1, wherein the hardware processor changes a gradation range used for forming the patch based on determination that the medium is a medium having a characteristic that a relationship between an increase/decrease in a developer and a reading gradation is partially inverted based on the reading result. ### Claim 10 (depends on 1) The image inspection system according to claim 1, wherein the hardware processor changes a design of the patch based on a characteristic of a contour of the patch based on a relationship between a background including the medium and the patch. ### Claim 11 (depends on 10) The image inspection system according to claim 10, wherein a change in the design includes a change in size of the patch. ### Claim 12 (depends on 1) The image inspection system according to claim 1, wherein the hardware processor changes the number of measurements of the patch or a size of the patch based on a degree of difficulty in reading the patch based on a relationship between a background including the medium and the patch. ### Claim 13 (depends on 12) The image inspection system according to claim 12, further comprising: a first notifier that makes a notification of correction accuracy of correction using the patch based on determination result of the degree of reading difficulty. ### Claim 14 (depends on 1) The image inspection system according to claim 1, further comprising: a user use history storage that stores the patch in association with a user. ### Claim 15 (depends on 14) The image inspection system according to claim 14, wherein the hardware processor controls formation of the patch on the medium according to a use history of the user. ### Claim 16 (depends on 14) The image inspection system according to claim 14, further comprising: a second notifier that makes a notification of formation of the patch according to a use history of the user. ### Claim 17 (depends on 1) The image inspection system according to claim 1, wherein the hardware processor controls, based on using a specific image included in user content as a patch, formation of the patch on the medium according to validity of the specific image as the patch.
